[ns] Which parameters are accessable in script for wireless medium

[Hajer FERJANI]

Hi,

May be you could replace :
"set ww cwnd_" by " set ww [$your_tcp_agent  tcl_method_to_return_cwnd] "
where "tcl_method_to_return_cwnd" is a tcl method defined in the command()
function of tcp class, which returns the cwnd_ param.

Bye.
